A little-known fact about the Fairlight Computer Musical Instrument, the first sampling synthesiser, introduced in 1979, is that it incorporated a psychotherapist called Lisa. Stressed musicians could key in an emotional problem and Lisa would begin the session with the soothing opening: ‘What is it that troubles you about x?’ She was flummoxed by a frivolous question from my husband, an early Fairlight owner, about a hole in her bucket but dealt expeditiously with my nine-year-old stepson.
